Starting Pitchers ERA-xFIP Differential
As we continue through trading season, I like to use a quick and easy method to figure out which starting pitchers to target if I am need of an additional arm. Though xFIP is not perfect of course, it is the best metric that sums up a pitcher’s underlying skill into one tidy statistic. Every once in a while, I will take the difference between a pitcher’s ERA and his xFIP to give me an idea of which pitchers have been the most fortunate so far and which have suffered from some bad luck. Of course, the idea is that the pitcher’s ERA should soon trend toward his xFIP, assuming his underlying skills used in the xFIP calculation do not change. This could provide fantasy owners with a potential buy low and sell high candidate list. Below are the five pitchers with the largest differentials between their ERA and xFIP in each direction.
